ABSTRACT:
A plastic additive containing thermoplastic polymer is provided in which the glass transition temperature of the thermoplastic polymer is from 40.degree. C. to 80.degree. C., and the plastic additive has magnetic particles dispersed therein. Also, a plastic composition containing an additive containing a thermoplastic polymer and plastic is provided in which the glass transition temperature of the thermoplastic polymer is from 40.degree. C. to 80.degree. C., and the plastic composition has magnetic particles dispersed therein. In addition, a molding formed of a plastic composition containing an additive containing thermoplastic polymer and plastic is provided in which the glass transition temperature of the thermoplastic polymer is from 40.degree. C. to 80.degree. C., and the molding has magnetic particles dispersed therein.
